Cloud helps business and IT create and deliver value in fundamentally new ways

Enable new IT and business

processes that break down

traditional silos and simplify

access to information in order

to deliver better business

outcomes.

Deliver IT without boundaries

Speed the delivery of new

offerings and services by

creating new models of self-

service and deployment.

Improve speed and dexterity

Empower internal and

external communities to

define and create new

offerings and services.

Create new business value


Businesses are choosing a variety of cloud models to meet their unique needs and priorities.

Private cloud

Hybrid IT

Public cloud

Appliances, pre-integrated systems and

standard hardware, software and networking.

Traditional IT

On or off premises cloud infrastructure

operated solely for an organization and

managed by the organization or a third party

Available to the general public or a large

industry group and owned by an

organization selling cloud services.

Traditional IT and clouds (public and/or private) that

remain separate but are bound together by technology

that enables data and application portability


Adoption patterns are emerging for successfully beginning and progressing cloud initiatives

IaaS: Cut IT expense and complexity through a cloud enabled data center

PaaS: Accelerate time to market with cloud platform services

SaaS: Gain immediate access to business solutions on cloud

BPaaS: Innovate business models by becoming a cloud service provider

What is IBM Workload Deployer?

An hardware appliance that helps reducing risk / errors by codifying infrastructure and taking

a declarative approach to your application environments

It offers choices for delivering services in your private cloud

– Existing middleware, virtual systems, virtual applications

Reduces time and effort in installation, configuration, and integration of application

environments

Simplifies monitoring and management for your application environments

Patterns

Existing Middleware

VMware, PowerVM, z/VM


Why leveraging a pattern-based approach

Creation of middleware

infrastructure takes too long

Manual or semi-automated

efforts are error-prone

Poor resource utilization results

in increased cost of labor and

hardware

Bugs are introduced by inconsistent configurations – 30%

Often most difficult variety of bugs detected during the

move from development to QA or production

Setting up an environment is expensive, so there is an

incentive to hold onto it “just in case” – even when no

longer needed

Slow down in technology adoption

Future environments require new hardware, instead of

recycling returned hardware; cycle repeats

Avg. lead time to get new application up – 4 to 6 months

Delay caused by approvals, procurement, shipment,

hardware installation, license procurement, OS

installation, application installation, configuration

Building a virtual system pattern

Virtual system patterns are built by combining parts from Hypervisor

Edition images

– Parts correspond to middleware components that you use to define your

topology

– Combine parts from multiple images in a single pattern

Example: Parts available in a WebSphere Application Server image

By leveraging a pattern-based approach you can:

Build a new system in minutes

Fully automate the deployment process

– Remove inconsistency between deployment

– Build and create the SAME system as many time as you want in a consistent

way!

Better utilize the systems’ resources:

– Better usage of HW resources

– Better usage of licenses!

Easily move from an HW platform to another

– Just choose another deployment platform and create the SAME system there


Why leveraging a workload-based approach

Delivered as full solutions, tailored for a use case:

– Web application

– Database

– Batch

– Analytics

Optimized-for-purpose results in limited ability to customize

– Database-as-a-Service

Reduce TCO through higher performance application foundations

Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon many factors, including considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results similar to those stated here.

Performance data is based on WebSphere Application Server in a distributed environment

Transactional Integrity

IBM has been doing this right for 40+ years

No transaction is ever lost or violated with WebSphere application

infrastructure’s built-in transaction integrity

WebSphere Platform designed as a transactional server from

Day One.

– For all transaction protocols (XA, OTS, WS-AT)

– On all platforms

WebSphere transaction costs are “pay-as-you-go”

– WebSphere fully optimized for 1PC and dynamically engages 2PC only after a 2nd resource is used

– Distributed transaction contexts created dynamically only during the first remote request in a transaction

– No change to application configuration as it engages 2PC or distributed transactions the “simplest” configuration always works.

Flexible configuration

– e.g. Per-application resource commit-ordering for DB/JMS scenarios


WebSphere Application Server: HA Architecture – A Brief Review

High Availability Architecture provides:

Peer Recovery Model with Active Hot Standbys for persistent

services

– Transactions

– Messaging

If a JVM fails then any Singletons running in that JVM are restarted

on a Peer once the Failure is detected

Starting on an already running Peer eliminates the start up time of a

new process which could take minutes

Planned failover takes a few seconds

This low failover time means WAS can tolerate many failures

without exceeding the 5.5 minute yearly maximum outage dictated

by 99.999%

Failure Scenario:

– Client calls EJB which updates database using 2PC transactions – Failure during in-process transaction (after the prepare statement) – Database record is locked until transaction is recovered (committed or rolled back)

WAS-ND HA – HA Manager detects the failure – Failover to a peer server which recovers the transaction log (shared on a NAS)

from the failed server – Recovery in a few seconds

Distribution and Consistency Services (DCS)

Reliable Multicast Messaging (RMM)

Workload Management (WLM)

Data Replication Services (DRS)

On-Demand Configuration (ODC)

WAS-ND JVM


High Availability Improvements

Improved HA support for messaging applications

– Reconnect to a standby gateway queue manager when an active queue manage fails or becomes available

Resource failover and retry logic for relational datasources and JCA connection factories

– Simplifies application development

• Minimizes the application code required to handle failure of connections to relational databases and other JCA resources

• Provides a common mechanism for applications to uniformly respond to planned or unplanned outages

– Administrator can tailor datasources and connection factory configuration based on application needs:

• number of connection retries

• alternate/failover resource

• pre-population of alternate/failover resource connection pool

• auto failback

– Full control of functionality available to scripts and programs via management MBean

Improved reliability & performance with DB2 – Support for client affinity & client reroute for apps that use IBM DB2

– New location transparency for EJBs using DB2 connections

Improved transactional integrity

– Support for shared DB locks between transaction branches and integration of new programming models with WAS proven transaction engine

Reduce unexpected and expected operational down time


IBM Installation Manager

Full local & centralized product lifecycle management:

– Install/Uninstall

– Update/Rollback (Fixpacks and iFixes)

– Modify (Add/Remove features)

Installs exactly the desired level of service in one pass

– No need to install GA product first and then apply a fixpack and/or ifixes as a

separate step

Lays down binaries relevant to user selections and system

environment

GUI & response file modes of operation

– GUI to perform individual operations

– Response files can be recorded from the GUI or created by specifying the

appropriate xml

– Silent mode support for invoking multiple operations

Single user experience across WAS, WAS components &

various IBM products

– A single instance of IIM can manage the product lifecycle for any IM based

products, from WebSphere, Rational, etc.

– Support for WAS, IHS, WCT, etc.

Agenda

Cloud Computing









WXTR extends IBM Transaction Processing on System p

Modern COBOL application deployments today are in conjunction with WebSphere Application Server – Often traditional distributed applications are integrated with WAS presentation and business logic

WXTR delivers increased deployment choices for distributed customers – Strengthens WAS position on supporting a range of programming choices

– TXSeries still an option for loose coupling or stand-alone legacy applications

Allows competitive positioning against other distributed TPM solutions, such as MicroFocus Server and Clerity Unikix, to provide a modernization path for COBOL customers on distributed platforms

– Can also provide a new option for existing IBM TXSeries customers

System Management – Concepts & Introduction

76


Unified System Administration

Integrated system administration experience

– Management of COBOL Container runtime using WebSphere administrative

console

– WebSphere administrative (wsadmin) scripting program support

– Start-up and shutdown of the COBOL container runtime processes are

coordinated with WebSphere Application start-up and shutdown actions

WebSphere wsadmin.sh utility


» Synchronized start and stop of WXTR with WAS

» WXTR gets started and stopped automatically when WAS is started or

stopped.

Handling WXTR container lifecycle


Handling WXTR container lifecycle

WAS is started through startServer.sh command.– This internally does various things including starting of various OSGI bundles

An OSGI bundle has been added to WAS runtime by WXTR to synchronize WXTR container lifecycle activities like start, stop and recovery with WAS

In WXTR OSGI bundle, we call the startCICSServices and stopCICSServices utilities ( indicated by “WXTR admin utilities” in the below diagram ) to handle start, stop and recovery.

Thus when WAS is started WXTR also gets started and when WAS is stopped WXTR also gets stopped


Application Development

Integrated Application development and deployment experience using IBM Rational tools:

– Build and Run applications on the fly • Automatic deployment of COBOL applications

– Mixed language debugging support across Java EE and COBOL

applications • For example, Invoke COBOL program from Java EE, inspect the COBOL

program and back to Java EE using the same IDE

A Performance comparison with an alternate IBM solution – Throughput with COBOL and DB2 Load

86

Nature of the load • COBOL program with CICS calls. • SQL calls to DB2 • Distributed load in 70:30 ratio. 70%

SELECT and 30% Updates • Two Transactions, Single Database

table • Application tuning carried out for load

distribution • CTG in remote mode

Observations • For the same TPS, WXTR takes

lesser CPU resource compared to TXSeries
